otool -l_otool mac_otoole(2)

显然，我们需要做2件事。a 把这些库附带在app上 b 把他们的引用地址修改到正确的位置。

2 mkdir yourapp.app/Contents/dylib

在编译出来的app中，创建dylib目录

然后把所有需要的库复制过去

cp /usr/local/lib/lib01.dylib yourapp.app/Contents/dylib/

cp /usr/local/lib/lib02.dylib yourapp.app/Contents/dylib/

cp /usr/local/lib/lib03.dylib yourapp.app/Contents/dylib/

3 install_name_tool -change /usr/local/lib/lib01.dylib @loader_path/../dylib/lib01.dylib "yourapp.app/Contents/MacOS/yourapp"

install_name_tool 是苹果提供的用来修改dylib安装名称的命令。这个命令执行之后，再用otool -L 就可以看到变化了

yourapp.app/Contents/MacOS/yourapp:
